What should be done to ensure safety around the front and sides of operating engines?

Staying at least 30 feet away from the front and sides of operating engines is critical for ensuring safety due to the hazards associated with jet blast and intake suction. Jet engines produce powerful forces that can project debris and create wind blasts capable of injuring personnel who are too close. Maintaining a safe distance of 30 feet minimizes these risks, allowing for safe operations around aircraft.

While signaling pilots or using communication methods like two-way radios are valuable practices for ensuring clear communication on the tarmac, they do not directly address the physical danger posed by the engines themselves. Wearing reflective clothing is important for visibility but does not mitigate the risks associated with proximity to operating engines. Therefore, maintaining a safe distance is the most effective method for ensuring safety in this environment.
